FERDINAND L. SCHMIDT, 0F NEW YGRLK, N. Y., ASSIGNO'RTG` UNITED STATES ENVELOPE I COMPANY, or SPRINGFIELD,

intense.

Be itknown that I, FERDINAND L. SCHMIDT,

the United States, residing at NewYork, in the county of New York and State of New York, have invented Aa new and useful Improvement in Envelop-Machines, of which the following is a specificay tion, accompanied by drawings, forming a, part of the sameLin which- Figure 1 is a plan View of an envelop machine embodying my invention. Fig. 2 is a side elevation, with parts shown in sectional View on the line 2-2, of Fig. l. Fig. l is a front elevation of a portion of the patch applying mechanism. Fig. 4 is a side View of the saine shown in sectional View.` Fig. 5 is a side View of the patch applying mechanism, shown in sectionalview, showing the'operative parts in position at the period of applying, a patch to an envelop blank, and Fig. 6 is a plan View of an envelop blank having an opening in the body portion covered by a transparent patch.

Similar reference characters refer to similer parts in the different figures. My present invention relates to an envelop machine for making what are known as a patch thereto,

use:

outlook envelops, or envelops in which the body of the envelop is provided with an.

openingadapted to register with an address written or printed upon an inclosure, said opening being covered with .a transparent patch which renders an inclosed address visible.

The objectI ofy my present invention is to complete the manufacture'of an outlook envelop upon a single machine, capable of lgumming the fiaps of the envelop, punching a hole or window in the body portion of the blank, gummingf around the 'margin of the window, applying a patch to the gummed margin for closing the opening and foldingy the flaps of the envelop, and this'object I ac-v complishby combining with theflap gumming and flap folding mechanisms of an envelop machine means for punching and gumming the window opening and applying as hereinafter described and point-ed out in the annexed claims.`

rlhe construction and operation of the lap gumming and Hap folding mechanisms will be well understood by those convex-sant withy envelop machines, andin the accompanying' drawings l have, therefore, shown so much posite end connected with' a vrounding the reciprocatingv punch 12y is a the opening IMSSACHUSETTS, A yCORPORATION OF MAINE' I Patented Sept. A7-,71915.

of an envelop machine as will be' necessary 55 to illustrate my ypresent invention.` The flap gumming mechanism comprises a table or support l for a stack or' pile of envelop blanksV 2, the topmostl blank of Iwhich is raised at stated periods by means of vertically reciprocating Hap gummin'g dies 3, 3, which are gummed by reciprocating gumming rolls 4, 4 taking gum at one en'd of their reciprocating movement'from a roll 5, which revolves partiallyf immersed in gum contained in the gum pan@` As. the

ytopmost blank is raised from the'stck 2, a

reciproca-ting; hooked conveyer 7 is moved. back over the stack of blanks in position to catch and. support the raised andguinmed envelop blank as. it `is stripped from the gumming dies by a stripping plate 8. The conveyer 7 then moves forward causing the blank, which is -engaged by the hooks 9, to be carried over a die plate 10 and into the 75 position indicated by the blank 11, F ig.' 1, in proper position to be punched by a vertically reciprocating punch 12 which, at the proper period,'ismade tofpass downward by suitableI actuating mechanism linto an opening 13 in the die plate 10, thereby forming an opening in the body of the envelop, such as that vshown at 14,14`ig. 6. `f

In the present instance the reciprocating punch 12 is connected by a link l5 with one 35 end vof alever 16 whichvis pivoted upon the framework of the machine, and has its opcam 161.. Sursleeve 17, connected by links 18 with af lever 90 '19 pivoted on the framework of the 'machine and operatively connected vwith an actuating cam, not shown. The sleeve 17 is preferably7 provided at its lower end with a yielding face 20 of rubber, or similarmaterial, to 95 which gum 'is applied by a. reciprocating' gumming roll 21 in the usualmannerof'ap; plying ad esive `materia1 to. the gumming dies of en felop machines. f'

The mechanism for holding the blank,un, 100 der the punch 12, punchingt the opening in theblank and gummingthe margin around forms no partof my present inf vention, it having been fully described in Letters Patent of the United States issued to me July 11, 1911,-No. 997,330,and the same is represented in the accompanying drawings simply for the purpose of showing its relative position to the iap gumming and flap folding mechanisms of the envelop machine. r W'lien the 'envelop blank has been punched 5 by the reciprocating punch 12 and die plate 10, hooks 22 on the conveyer carry the blank forward overa table 23and beneath a vertically reciprocating plunger 24 which, upon its downward movement, forces the body of 1ol the blank through an opening 25 in the table 23 upon a folding bed 26 where the flaps are folded by hinged flap folders 27, 28 and 28a in the method commonly practised in envelop machihes of this class. When the en- 'velop rests upon the table 23 in the position shown at 30, Fig. 1, and before the plunger begins its downward movement, a patch of transparent paper 29, Fig. 6, 1s applied to I the envelop blank to cover the opening 14.

Y` The patch 29 is of suiicient size to cover the gummed surface formed by the contact of the yielding 'gummed face 20 ofthe sleeve 17 with the envelop blank. A,

Thetransparent patch 29 is cu. from the end df a continuous `strip 31 taken from a coil 32 supported in the frame-work of the machine in ah elevated position in front of.

the folding mechanism. The mechanism for withdrawing the continuous strip from the 30 coil 32, cutting the-individual patch therefrom and applying the same to an envelop `Ablank is shown in sectional view in .Figp 2, but is represented on a larger scale in Figs. 3,'4 and 5the sectional` views represented 55 in Figs. 4-and 5 showingthe cutting and patch applying mechanisms in diiferent positions, that shown in Fig. 4 showing the cutting vmechanism in the position ofsever- `ing the patch from the continuous strip and Fig. irepresenting the severed patch as beino applied to the envelop blank.

he cpntinuous strip :is withdrawn from the coil- $2 by means of feed rolls 33 and 34,

the former of which is driven by a sprocket wheel 35 and chain 36 from a driving shaft 37, imparting a slow 4feeding movement to the continuous strip 31 by which it is pro- `jected through a tubular guideway 38 to the cutting mechanism, which comprises a sta- I 5 tionarycutting blade 39 .and a' movable cutting blade l40. :The movable cutting blade is carried in a swinging arm 4l piyoted on a vrocking shaft 42, and provided with ways 43 in which the movable sliding. The swinging witha central opening 44,. through. which pass downwardly projecting arms 45 carried by the rocking shaft 42. The arms 45 pass through a hole in the moyable cuttinglblade 40, andthe lower ends of the arins 45 ai-e connected by spiral springs 46 with studs 47 projecting from the lower end 'of the swinging arm 41. The swinging arm 41 is provided witha pressure plate 48, between arm 41 is provided ,6 which and the stationary cutting blade 39 blade is capable off the free end of the continuous strip 31 is clamped by the swinging movement of the arm 41. An intermittent rocking motion is given to the shaft 42 and arms 45 by means of a radial arm 49, carried on one end of the rocking shaft 42 and connected by a link 50 with a suitable actuating camcarried upon the shaft 37.

iVheu the arm 4l is swung away from the stationary blade 39, as shown in lP ig. 5,`the end of the continuous strip 31 is moved forward over the corner of the stationary blade 39 a suilicient distance to form the width of the patch 29. given to the arm -1-1 tov carry it from, the position shown in Fig. 5 to the position shown in Fig. 4, the arm 4l being drawn forward byl means of its spring connections 46 with the ends ot the arms 45. During this swinging movement oit' the arm 41,- the movable cuttiiig-blzulc 40 is held retracted within the ways 43 until the pressure plate A swinging movement is then 48 clamps tli`e end ot the continuous strip against the stationaryI cutting blade 39 thereby stopping the forward 'movement of 4 the arm 41. The continued movement of the arms 45 will then slide the movable cutting b lade in its ways 43 over the edge of the stationary cutting blade 39, thereby severing the individual patch from the continuous strip.A

The severed patch is then held firmly between the pressure plate 48 and the sta-tioiary lcutting blade 39, with the lower edge of the patch covering the open ends 51 of a pair ofsuction tubes 52. carried upon a hollow i'ocking shaft The suction tubes 52 communicate with the hollow shaft 53, and the latter is connected by a iiexible tube 54 with a pump or other suitable mechanism, not shown, for exhausting the air from the suction tubes 52 during their. period of'contact with the severed patch.

As soon as the patch has been severed from the end of the continuous strip, the

motion of the rocking shaft 42 is reversed,

swinging the arms 45 away Jfrom thesta-v tionai-y cutting blade 39 into the position shown in Fig. 5, and again providing a ree space between the stationary cuttinotblade 39 and the pressure plate 48 for thelzie'eding movement of the continuous strip, but :leaviingthe severed patch securely held against' the open ends of the suctio'nftubes 52. The

rockingr shaf 53,- which carries the suction' 112e tubes 52, Vis then rocked by means of a radial arm 55 and link 56 which connects the radial arm 55 with a suitable actuating cam, nht shown, on the shaft 37. The-rocking vInovement of the shaft 53 carries the suction tubes 52 from a vertical position to a horizontal'v position, as shown by the broken lines 57,

When thesuction tubes have. been broughtl intotliefhorizontal position,`

indicated by ,thebrokenv lines 57, Fig.y al, a rocking movement iis' imparted to' the 'cam 6l which forces the sliding: frame 58 rearward, thereby moving Vthe.y s'uctionfltubes 52 Vfromthe position shoyyn by thebroken lines 57 to the position :shown by the brokeny lines y65 and beneathhe reciprocating plunger .24;

A second rocking movement is then given to the; hollovvirocking shaft 53, by which the open .ends ofthe suction tubes 52am depressed to carry the "severedA patcliiv held thereon into Contact `With thegummed surtace of ,the :envelop blank As soon as .the

-with the opening.l
